Interfacing
Interfaces
To host system: Ethernet 10/100baseT, UDP messaging.
To front-end devices: Fiber-optic loop, 10 Mbit/sec serial, 9 bit asynchronous binary.
Host computer
PSI Diagnostic host software recommended.
Libraries available for Microsoft® .NET 2.0, Win32 and LabVIEW.
Connectors
Ethernet
RJ-45 socket, suitable standard Ethernet 8-way plug and CAT5 or higher
cable. Fully transformer isolated
Auto MDIX capability: The A500 negotiates TX and RX lines when making
a connection. Either crossover or non-crossover cables may therefore be
used.
Fiber optics
Five pairs (in base A500), 1mm Avago HFBR ST bayonet.
Power in
2.1mm threaded jack. Mates with Switchcraft S761K or equivalent.
